Hab. in Costa-Bica et Veragua. 



The portion of the great Central American Isthmus occupied by the Bepublic of Costa 

 Eica and the adjacent Province of Veragua is the seat of a peculiar fauna, which contains many 

 very remarkable forms. The most striking of these are the wonderful Bell-bird with three 

 caruncles (Chasmorhynchus tricarunculaius), and the bare-throated Umbrella-bird (CepJiahpterus 

 glabricollis). A number of very beautiful and peculiar Humming-birds are also found in this 

 district, of which Panterpe insignis, Michrochera albicoronata, and several species of Oreopyra 

 stand pre-eminent. Other groups are well represented by distinct species, and even in some 

 cases by peculiar genera. Amongst the former, the bird we now figure is one of the most 

 beautiful as well as interesting for the marked features of its specific characters. 



The first specimens of this bird were obtained for Messrs. Salvin and Godman by Enrique 

 Arce, near Tucurriqui, a village of Costa Eica, situated in a small plain surrounded by hills on 

 the eastern slope of the Cordillera, and at an elevation of about 3000 feet above the sea level. 

 These were described by Mr. Salvin in the " Proceedings of the Zoological Society" for 1864. 

 Other examples were subsequently obtained for the Smithsonian Institution by J. Carmiol, at the 

 villages of Angostura and Payariqui in Costa Eica, as recorded by Mr. Cassin. During his 

 subsequent expeditions in Veragua Arce appears to have frequently met with this bird, as 

 specimens were included in each of his collections sent from the villages of Santa Fe and Santiago, 

 as well as from the Cordillera of Tole. Southward of Santa Fe no specimen has been hitherto 

 encountered, the species being as yet unknown on the Isthmus at Panama, nor have any of the 

 collectors who have visited districts immediately to the south met with it. To the northward of 

 Costa Eica it is equally unknown, so we may fairly presume that this fine bird is restricted in 

 its range to the above-mentioned localities.
